A fenestrated endograft having an expandable stent frame and a lumen is described herein. The stent frame has a proximal end portion, a distal end portion, and a central portion. The central portion may include a fabric that has an aperture partially surrounded by part of the expandable stent frame. The lumen extends through the proximal end portion, the central portion, and the distal end portion. The stent frame is radially expandable from a collapsed configuration to an expanded configuration. The central portion is coupled to a fabric, which extends about a perimeter of the central portion. The fabric has an aperture with a cross-sectional dimension that is substantially equal to a cross-sectional dimension of an outer cross-sectional dimension of the distal end portion. The central portion has a curved elongate member, which includes a curved segment extending around at least one-fourth of a perimeter of the aperture.
